triangulation

The season of 1835–36 was employed in carrying on the triangulation; in which Colonel [George] Everest was much impeded by a long continuance of hazy and cloudy weather. It appears, however, that the principal triangulation was brought down to the line from Juktipura to Pagara; […]

[…] I have placed myself in communication with the Astronomer Royal, for the purpose of considering the steps necessary to be taken to effect the connexion required, between the triangulation of Great Britain and that of Belgium. […] I have also placed myself in communication with General Nerenburger, Director of the Dêpot de la Guerre at Brussels, and have received from him the diagram of the Belgian triangulation, with descriptions of the stations with which it is necessary to connect our triangulation, and we possess a copy of the triangulation of France.

The King has been said to indulge in a process called Triangulation. The word is harder than the idea. The basic fact is that the King can move to an adjacent square in one move, two moves or three moves, without returning to its point of origin.

Regular triangulations are a class in-between lifting and lexicographic triangulations. Their main draw-back in the context of this paper is that regularity depends on the specific realization and not only on the oriented matroid.

A special advantage of radar is that it works during darkness and other periods of low visibility, which prevent visual triangulation and aircraft techniques for measuring nuclear clouds.

Triangulation was a presidential leadership strategy that presented the president as having borrowed elements of both the right and the left to develop some form of center policy amalgam.

One recent attempt to combine both forms of data collection […] was based on a parallel methods approach, in which the results of two similar but separately located studies were triangulated. Triangulation entails overlapping the results at several points to enhance reliability. […] Other documented research has attempted to gain a broader view through the triangulation of two sets of data (quantitative and qualitative) on the same question, taken from the same respondents in a single study.
